Comparing: M7 vs. Pz.Kpfw. IV hydrostat. vs. Type 3 Chi-Nu

Development started in 1941. Initially, the vehicle was developed as a light tank; however, as the model gradually received extra armor and armaments, it was reclassified as a medium tank. Production of the M7 started by the fall of 1942. However, since the M7 was inferior to the mass-produced M4 Sherman in all parameters except speed and dimensions, the production was stopped. A total of 7 vehicles were produced.

This experimental version of the Pz.Kpfw. IV Ausf. G, incorporating hydrostatic drive, began development in 1944. Trials were discontinued due to the unreliability of the transmission and the lack of spare parts.

The Type 3 Chi-Nu medium tank is a modification of the Тype 1 Chi-He with a new turret and gun. The tank was the most powerful among wartime Japanese mass-produced vehicles. However, only 60 vehicles were manufactured due to shortages of components and materials.
